In some cases this may be an artifact of the scanning process, but more often the pictures were not positioned evenly in the original book. Page numbers shown in brackets [ ] held illustrations without text. They will sometimes be out of sequence with adjoining page numbers. A few typographical errors have been corrected. They have been marked in the text with mouse-hover popups. HENRY FROWDE, M.A. PUBLISHER TO THE UNIVERSITY OF OXFORD LONDON, EDINBURGH, NEW YORK TORONTO AND MELBOURNE THE THEORY AND PRACTICE OF PERSPECTIVE BY G. A. STOREY, A.R.A. TEACHER OF PERSPECTIVE AT THE ROYAL ACADEMY ‘QUÎ FIT?’ OXFORD AT THE CLARENDON PRESS 1910 OXFORD PRINTED AT THE CLARENDON PRESS BY HORACE HART, M.A. PRINTER TO THE UNIVERSITY DEDICATED TO iii SIR EDWARD J. POYNTER BARONET PRESIDENT OF THE ROYAL ACADEMY IN TOKEN OF FRIENDSHIP AND REGARD v PREFACE IT is much easier to understand and remember a thing when a reason is given for it, than when we are merely shown how to do it without being told why it is so done; for in the latter case, instead of being assisted by reason, our real help in all study, we have to rely upon memory or our power of imitation, and to do simply as we are told without thinking about it. The consequence is that at the very first difficulty we are left to flounder about in the dark, or to remain inactive till the master comes to our assistance. Now in this book it is proposed to enlist the reasoning faculty from the very first: to let one problem grow out of another and to be dependent on the foregoing, as in geometry, and so to explain each thing we do that there shall be no doubt in the mind as to the correctness of the proceeding. The student will thus gain the power of finding out any new problem for himself, and will therefore acquire a true knowledge of perspective. vii CONTENTS BOOK I P AGE THE NECESSITY OF THE STUDY OF PERSPECTIVE TO PAINTERS, SCULPTORS, AND ARCHITECTS WHAT IS PERSPECTIVE?
